(mongodb >=1.0.0)

MongoDB\Driver\Manager::executeBulkWrite — Execute one or more write operations

说明

final public MongoDB\Driver\WriteResult MongoDB\Driver\Manager::executeBulkWrite ( string $namespace , MongoDB\Driver\BulkWrite $bulk [, MongoDB\Driver\WriteConcern $writeConcern ] )

Executes one or more write operations on the primary server.

A MongoDB\Driver\BulkWrite can be constructed with one or more write operations of varying types (e.g. updates, deletes, and inserts). The driver will attempt to send operations of the same type to the server in as few requests as possible to optimize round trips.

参数

namespace ( string ): A fully qualified namespace (e.g. "databaseName.collectionName").
bulk ( MongoDB\Driver\BulkWrite ): The MongoDB\Driver\BulkWrite to execute.
writeConcern ( MongoDB\Driver\WriteConcern ): Optionally, a MongoDB\Driver\WriteConcern to apply to the write operation. If none is given, the write concern from the MongoDB Connection URI will be used.

返回值

Returns MongoDB\Driver\WriteResult on success.

错误／异常

Throws MongoDB\Driver\Exception\BulkWriteException on any write failure (e.g. write error, failure to apply a write concern)
Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.
Throws MongoDB\Driver\Exception\ConnectionException if connection to the server fails (for reasons other than authentication).
Throws MongoDB\Driver\Exception\AuthenticationException if authentication is needed and fails.
Throws MongoDB\Driver\Exception\RuntimeException on other errors.

范例

Example #1 MongoDB\Driver\Manager::executeBulkWrite() example

  <?php

$bulk  = new  MongoDB \ Driver \ BulkWrite ();

 $bulk -> insert ([ '_id'  =>  1 ,  'x'  =>  1 ]);
 $bulk -> insert ([ '_id'  =>  2 ,  'x'  =>  2 ]);

 $bulk -> update ([ 'x'  =>  2 ], [ '$set'  => [ 'x'  =>  1 ]], [ 'multi'  =>  false ,  'upsert'  =>  false ]);
 $bulk -> update ([ 'x'  =>  3 ], [ '$set'  => [ 'x'  =>  3 ]], [ 'multi'  =>  false ,  'upsert'  =>  true ]);
 $bulk -> update ([ '_id'  =>  3 ], [ '$set'  => [ 'x'  =>  3 ]], [ 'multi'  =>  false ,  'upsert'  =>  true ]);

 $bulk -> insert ([ '_id'  =>  4 ,  'x'  =>  2 ]);

 $bulk -> delete ([ 'x'  =>  1 ], [ 'limit'  =>  1 ]);

 $manager  = new  MongoDB \ Driver \ Manager ( 'mongodb://localhost:27017' );
 $writeConcern  = new  MongoDB \ Driver \ WriteConcern ( MongoDB \ Driver \ WriteConcern :: MAJORITY ,  100 );
 $result  =  $manager -> executeBulkWrite ( 'db.collection' ,  $bulk ,  $writeConcern );

 printf ( "Inserted %d document(s)\n" ,  $result -> getInsertedCount ());
 printf ( "Matched  %d document(s)\n" ,  $result -> getMatchedCount ());
 printf ( "Updated  %d document(s)\n" ,  $result -> getModifiedCount ());
 printf ( "Upserted %d document(s)\n" ,  $result -> getUpsertedCount ());
 printf ( "Deleted  %d document(s)\n" ,  $result -> getDeletedCount ());

foreach ( $result -> getUpsertedIds () as  $index  =>  $id ) {
     printf ( 'upsertedId[%d]: ' ,  $index );
     var_dump ( $id );
}

 
 if ( $writeConcernError  =  $result -> getWriteConcernError ()) {
     printf ( "%s (%d): %s\n" ,  $writeConcernError -> getMessage (),  $writeConcernError -> getCode (),  var_export ( $writeConcernError -> getInfo (),  true ));
}

 
 foreach ( $result -> getWriteErrors () as  $writeError ) {
     printf ( "Operation#%d: %s (%d)\n" ,  $writeError -> getIndex (),  $writeError -> getMessage (),  $writeError -> getCode ());
}
 ?>

以上例程的输出类似于：

Inserted 3 document(s)
Matched  1 document(s)
Updated  1 document(s)
Upserted 2 document(s)
Deleted  1 document(s)
upsertedId[3]: object(MongoDB\BSON\ObjectID)#5 (1) {
  ["oid"]=>
  string(24) "54d3adc3ce7a792f4d703756"
}
upsertedId[4]: int(3)
